Digital image analysis is the field of extracting relevant information from digital images. Recent developments in imaging techniques have made 3-dimensional volume images more common. This has created a need to extend existing 2D image analysis tools to handle images of higher
This thesis presents work in digital image cytometry applied to fluorescence microscope images of cultivated cells. Focus has been on the development and compilation of robust image analysis tools, enabling quantitative measurements of various properties of cells and cell structures. A significant
The increasing popularity of computer animation and the affordable price of both software and hardware have drawn lots of independent animators to design their own small productions. However, in these animators’ productions, consideration given to visual content quality usually overrides audio quality,
We have under a 10 week period been producing a part of Peter Martinsson’s short movie Eve. He had an aesthetic vision and we handled the technical part. This meant that we couldn’t change the core idea behind the movie but we
Face orientation estimation is an important topic in computer vision and pattern recognition, and in particular, more recently in some emerging, media-related applications. Due to the non-rigid properties of faces, it is computationally expensive and in general difficult to achieve good estimation
With the advancements of mobile communication technologies, the utilization of audio-visual information in addition to textual information becomes more prevalent than the past. Cryptographic approaches are therefore necessary for secure multimedia content storage and distribution over open networks such as the Internet.
Due to the increasing use of hand-held camcorders, an explosion of home video data is already underway. Home videos, by nature, are unedited, unstructured and lack of story-line. They contain unrestricted content domain which usually mixes together with irregular camera motions. These
This report addresses the problem of software correction of spatially variant blur in digital images. The problem arises when the camera optics contains flaws, when the scene contains multiple moving objects with different relative motion or the camera itself is i.e. rotated.
Image rendering is the process of creating realistic computer images from geometric models and physical laws of light and reflection. This master thesis deals mainly with the numerical intricacies of implementing an image renderer using spherical harmonics. It investigates how to calculate
This thesis investigates possibilities to perform image interpolation on an FPGA instead of on a graphics card. The images will be used for 3D display on Setred AB’s screen and an implementation in firmware will hopefully give two major advantages over the
